Tracen Academy!
This school, nestled in the heart of Japan, is hailed as the most prestigious sanctuary for nurturing horse girls in the entire country.
Here, countless elite horse girls gather, their lithe figures and relentless determination weaving legends on the racetrack.
Horse girls—uma musume—are a unique race in this world. Outwardly indistinguishable from humans, they possess extraordinary physical and athletic abilities, with their animal ears and flowing tails serving as their distinctive symbols.
And many of these horse girls, driven by their passion for racing, step onto the track as professional competitors—racehorse girls.
Tracen Academy is the very place where these racehorse girls chase their dreams. To shine on the racetrack, they undergo the most rigorous training. The thriving racing scene has also drawn countless spectators, pushing prize money to staggering heights and bringing immense rewards to both the academy and the horse girls themselves.
And that means—this is where the big money is!
Lin Anran believed this wholeheartedly, which was why he had crossed the ocean, leaving America behind to jump ship here.
Walking down the path, his cold, calculating gaze swept over the training fields, where enthusiastic young girls pushed themselves to their limits. Not once did his eyes linger on any one of them.
After weaving through the buildings bustling with students, Lin Anran finally stopped in front of a particular structure.
Unlike the others, this building saw little student traffic—mostly just faculty members coming and going. Clearly, this was where the academy's staff worked.
Stepping inside, Lin Anran made a beeline for the first-floor infirmary, pulling out a key he had recently obtained from the student council president.
Make no mistake—he wasn't here because he was feeling unwell and needed a checkup.
Rather, this infirmary was about to become Lin Anran's office, where he would serve as Tracen Academy's school physician.
But don't get the wrong idea. Lin Anran had zero interest in being some saintly, virtuous doctor.
A benevolent healer? No. A ruthless profiteer? Now we're talking!
He was determined to mercilessly—ruthlessly—drain Tracen Academy and its racehorse girls of their riches! He'd heal their legs, then take their prize money as his fee.
Lin Anran would establish himself here as Tracen Academy's special consultant physician, treating Japan's racehorse girls and lining his pockets in the process!
"So this is where I'll be working from now on."
"Tch. That 'Big Red' couldn't even win her debut race after getting bumped. And she wanted me to stay as her personal doctor? Not a chance!"
"Better to come to Japan and squeeze Tracen dry than starve with her!"
His words dripped with resolve, making his disdain for the aforementioned "Big Red" crystal clear.
The truth was—Lin Anran had arrived in this world several months ago, and with his arrival came a special cheat: the [Uma Musume Treatment System]!
As the name suggested, the system granted him [Basic Treatment Skills] specifically for horse girls, along with a one-time trial of [Intermediate Treatment Skills].
Notably, Lin Anran had first appeared in… America, not Japan.
Now, in any country—America, Europe, or Japan—doctors were well-paid professionals. But in a world where racehorse girls existed? Horse girl doctors were even more lucrative!
To test his abilities, Lin Anran had befriended some young racehorse girls in America, offering them free physical therapy and treatments. The results were impressive, and he planned to reel in bigger fish later.
Imagine a group of unproven, overlooked fillies, taken under the wing of a kind, older doctor who helped them train and recover. How could those inexperienced, pre-debut horse girls not be moved to tears with gratitude?
But Lin Anran knew—what kind of money could he really squeeze out of small fry like them? It'd only ruin his reputation and scare off future clients. If he was going to make bank, he needed to aim higher!
The problem was, as a fan of horse girl games and anime, he only knew about the Japanese prodigies—the ones destined for greatness. Like Tokai Teio, who aimed for the undefeated Triple Crown, or Silence Suzuka, a powerhouse who ran until her legs gave out… But those stars weren't in America.
So Lin Anran decided to play the long game. He kept building relationships with those no-name fillies, waiting for them to debut and eventually rub shoulders with high-stakes racehorse girls. Then he could start charging exorbitant fees.
Once he had that easy money in his grasp, he could do whatever he wanted!
Lin Anran saw himself as the ruthless, profit-driven underbelly of the horse girl world. Dreams? Competition? Meaningless. All that mattered was wealth.
But—
Reality had other plans.
The rookie horse girls he knew were nowhere near the caliber of Tokai Teio, Silence Suzuka, or Special Week. They were utter nobodies, struggling to even win low-tier stakes races—let alone their debut races!
"Big Red, Ruffian, Dahlia… None of the other horse girls even want to train with them. They all avoid them. That says everything about their skill level."
"And their internal training race results? Mediocre. Big Red, who won most of them, still only managed… fourth place in her debut race!"
The girl originally named "Big Red"—who Lin Anran had grown close to—had debuted under the uninspiring name "Secretariat". And yet… she lost her very first race.
In Lin Anran's memory, the top-tier horse girls from anime won their races spectacularly. Like Rice Shower, whose eyes practically burned with determination mid-race! Or Silence Suzuka, who left her competitors in the dust!
But the best of his American fillies—Big Red, no, Secretariat—couldn't even win a simple debut race. Fourth place? Pathetic.
It was clear—they were all small fry, not worth his time. If they couldn't even win their debuts, how could they ever introduce him to high-stakes racehorse girls?
Deeming his plan a failure, Lin Anran gave up shortly after treating Secretariat's post-race injuries.
Instead—he headed straight for Japan's Tracen Academy.
Compared to those American rejects, becoming a cutthroat doctor in Japan was the real golden ticket, right?!
"Secretariat, Ruffian, and Dahlia kept begging me not to leave, saying they'd hire me as their personal doctor once they debuted and give me a cut of their prize money."
"Yeah, right. Like I'm an idiot. If they can't even win their debut, what prize money are they gonna split with me?"
Lin Anran wasn't about to buy into any of that "dreams" or "bonds" nonsense. He was a cold, calculating adult.
He was the one who dished out empty promises, not the other way around!
Even if the prize split was generous, what good was it if they never won?
Sure, those girls had grown attached to him, and they were all stunningly beautiful, looking impressive in training races.
But when the strongest of them—Secretariat—couldn't even win her debut, it proved their so-called "training race dominance" was just a bunch of amateurs flailing around.
Before leaving, Lin Anran gave his final "encouragement" to the girls who clung to his sleeves, their faces a mix of disbelief and reluctance.
"Believe in yourselves. You all have talent. I'm not abandoning you—I just have business elsewhere…"
"Once you become the strongest, I'll come back. And then, no matter what you ask of me, I'll agree!"
Hiding his glee, Lin Anran fed them those lines, already scheming about how to milk Japan for all it was worth.
What he said, what he promised—none of it mattered.
After all, how could horse girls who couldn't even win their debuts ever become the strongest? That "promise" was nothing but empty comfort.
And so, Lin Anran bid farewell to his favorite American rejects and flew to Japan.
Today was his first day. Though he hadn't officially started work yet, he couldn't wait to scout the place and plan his future money-making schemes!
As he pondered, Lin Anran finally reached the infirmary. Unlocking the door, he stepped inside and took in his new surroundings.
Rows upon rows of medicine greeted him.
"The problem is, I only have [Basic Treatment Skills] right now. Based on past experience, I can't fully heal serious injuries."
"If I'm only treating minor stuff, making big money won't be easy…"
Lin Anran knew his current abilities were just average doctor-level, far from miraculous.
What he wanted was the power to turn tragedy into routine—to heal fractures and career-ending injuries with ease. At that level, top-tier racehorse girls would throw fortunes at him to fix their bodies.
Then, making money would be effortless! But to reach that point, he needed at least [Intermediate Treatment Skills]…
Lin Anran hadn't come to Japan just because he knew some of its horse girls. No—this was where he could advance his skills!
"Open panel."
Instantly, a floating screen visible only to him appeared, displaying a few lines of text.
[Racehorse Girl Treatment System]
[Mission: Win the Triple Crown Races]
[Shape-shifting Participation Available]
[Reward: Permanent Intermediate Treatment Skills Upgrade, Two Advanced Treatment Skill Trials]
Before Lin Anran's eyes was the system panel, outlining his path to becoming a miracle doctor.
Win the Triple Crown, ascend to medical mastery! This was a crucial step in his grand plan.
By his estimation, his current [Basic Treatment Skills] made him a competent physician.
But for injuries like those suffered by Tokai Teio or Silence Suzuka in the anime—he was useless.
Severe fractures like those required year-long recoveries, devastating careers. Even the most expensive specialists couldn't guarantee perfect healing.
But [Intermediate Treatment Skills] could change that. The value of such an ability—and the fees he could charge—were beyond imagination.
As for the even rarer [Advanced Treatment Skills], Lin Anran suspected they could heal career-ending injuries.
But that was a distant dream. If [Intermediate Treatment Skills] required winning the historic Triple Crown, what impossible feat would [Advanced Treatment Skills] demand?
For now, he had to start with step one. If he couldn't even win the Triple Crown, the rest was out of reach.
And so, Lin Anran had crossed the ocean to Japan, accepting the system's challenge: conquer Japan's Triple Crown races.
His target? The Japanese Classic Triple Crown—the most prestigious, highest-paying series in the horse girl world!
"I have to win the Triple Crown. The prize money is insane."
"The American Triple Crown is way harder, and the payout isn't even much better. Only an idiot would go for that."
"This way, I can earn double—prize money as a racehorse girl, and fees as a doctor!"
The thought of double income set his heart ablaze.
But now, only one question remained:
What kind of racehorse girl would he transform into, and how strong would she be?
If he ended up as some weakling like Big Red, unable to even win a debut race… then his plan would crash and burn before it even began.
"Please, let me get a strong transformation."
Transforming into a girl—a horse girl, no less—was a little embarrassing. But to this profit-obsessed doctor, shame was nothing compared to cold, hard cash.
With that, Lin Anran pressed the "Draw" button.
[Racehorse Girl Doctor Competition Template Activated]
[Transformation Character Available]
[Random Selection in Progress…]
And then—
The panel displayed several familiar, utterly shocking character portraits.
These weren't from Uma Musume. They were from another game Lin Anran had played—Arknights!
Like a gacha pull, the screen cycled through illustrations he never expected to see again.
"Huh? [Amiya]? That's a donkey, not a horse girl!"
"[Nearl]? PANTHEON?!"
"[Blemishine]?"
"Old hag? [Kal'tsit]??"
"Wait, why is [Młynar] here?! This isn't Horse Boy!"
The usually composed, ruthless school doctor was stunned speechless.
But finally, the screen settled on a petite, slender girl with snow-white hair.
Her eyes were half-lidded with laziness, her long, silvery locks cascading down her back. Her youthful frame hinted at curves yet to fully develop, her slender waist not entirely hidden.
Despite her delicate, doll-like appearance, she exuded an "approach at your own risk" aura, as if she'd seen too much and couldn't be bothered anymore. The contrast was striking.
At first glance, one might worry if such a fragile-looking girl could actually compete on the racetrack.
Beneath her portrait was her name—[Platinum · Centaurea]
In the game, she was an archer—a Sniper Operator who seemed like a harmless, lazy girl.
The identity he'd transform into, the one who'd race against other horse girls, was…
Lin Anran's pupils contracted sharply.
Platinum?!
Lin Anran hadn't paid much attention to Arknights' convoluted lore, but he knew the basics.
In his memory, Platinum's real name was Centaurea, a member of the Kuranta race from Terra—a species based on horses, complete with horse ears and tails, just like horse girls.
Originally an idol knight, she later became a high-ranking assassin in the Armorless Union, earning the codename "Platinum."
But in truth? She was a lazy girl who just wanted to slack off.
"Can she… actually win?!"
[Real Name: Centaurea]
[Codename: Platinum]
[Race: Kuranta]
[Height: 160cm]
[Current Growth Stage: 5%]
[Surface Compatibility: Turf (A), Dirt (B)]
[Distance Compatibility: Sprint (B), Mile (A), Intermediate (A), Long (B)]
[Running Style Compatibility: Leader (B), Frontrunner (A), Stalker (A), Closer (A)]
[Unique Skill: ??]
[Note: The more racehorse girls you treat (and the better the treatment), the faster growth stage and unique skills improve.]
[Treated So Far: Big Red (Minor Injury - 100% Recovery)]
[Treatment Reward: Growth Stage +5%, Slight Increase in Racehorse Girl Strength, Horse Nip+10% (Pre-Transformation)]
Staring at Platinum's stats, Lin Anran was floored.
Her compatibility—she's an all-rounder?!
And the growth stage was a horse girl's rapid development phase, like a growth spurt. Platinum could enter that too?
Not only that, but the more racehorse girls he treated—and the better he healed them—the stronger Platinum would become?
Though… what was this "Horse Nip+10%" about? He'd heard of catnip, but horse nip? Probably irrelevant. If it didn't make money, he'd ignore it.
"This changes everything—!"
Even if his "glass-cannon ADC Platinum" wasn't strong enough to win G1 races yet, the more he treated, the more she'd improve!
He could save fillies → win races → earn money → improve skills → repeat! A perfect cycle!
This revelation made the profit-hungry doctor's eyes gleam, his nonexistent medical ethics surging to new heights!
Right now, he could only treat minor injuries. How much could that really earn him?
But race prizes and treating critically injured horse girls? That was real money. And now, by healing more horse girls and racing more, he could get stronger as both a doctor and a competitor!
Sitting in his office chair, lost in thought about races, money, and transformations, he suddenly heard footsteps approaching.
Then—knocking.
Knock, knock, knock…
The sound was sharp, urgent—like someone in a hurry. It snapped Lin Anran out of his scheming.
Was that…
A patient on his very first day?
After a brief pause, Lin Anran perked up and called out.
"Come in."
The door swung open.
A petite, delicate-looking racehorse girl hobbled in on crutches.
"Doctor… can you heal my leg?"
Her voice trembled with hope and nerves as she gazed up at him.
Lin Anran immediately recognized her.
This was Tokai Teio—one of the most valuable, high-earning racehorse girls in his eyes! To think he'd meet her on day one?!
Suppressing a grin, the ruthless doctor nodded solemnly.
"Yes."
"A doctor's duty is to heal. Leave your body and your priz— ahem, your worries to me."
